My Ubuntu headless server, I call it "guanabana" ...
... is always on! One time it was on for almost 4 months I think. It used to be a webserver so was kind of funny to see how hackers tried to get in , hahahaa....
My new Mac Mini is also on, all the time. And has daily backups as well.
I don't usually travel for more than a few weeks, so I keep them on anyway, unless a storm is coming (possible power issues)
By the way, most Linux based computers run better that way. Every reboot cleans up RAM, so that's bad for performance. Unless is Window$, of course, lol ... that's a different story ...
